Preparation and Photocatalytic Property of CuO/SnO_2/TiO_2 Nanocomposite

The CuO/SnO2/TiO2 nanocomposite has been prepared by the sol-gel method,in which the CTAB was used as engaged-template that reacted with Cu(NO3)2、SnCl2 andTi(OC4H9)4.The nanocomposite as-obtained was characterized by SEM,XRD,IR and UV-vis.The CuO/SnO2/TiO2 nanocomposite was composed of anatase crystal TiO2 and rutile crystal SnO2 and monoclinic crystal CuO.Under sunlight the photocatalytic activity of CuO/SnO2/TiO2 nanocomposite as-obtained was studied by methyl orange as simulation pollutants.The CuO/SnO2/TiO2 nanocomposite had excellent photocatalytic activity.
